allocator: Fix Array parsing to slice parsing (#346)

Fixes a bug where the `--target` parameter was being ignored due to the
flag parsing using `GetStringSlice` when the flag decaration is `Array`.

The bug changes the type from an ArrayString to SliceString.

Additionally, fixes `--maintenance` call which is missing a region value.
